Which wire. Follow the smoke to the wire on the wrong screw, along with a ground.

No smoke just gets hot and does not blow fuse strange deal. If I bypass that saftey "N" switch and hook up cable to battery it turns over automatically

Is it the original control box or has someone splined it to engine? The Yammmerc's are wired different..

Further diagraming (with a bit of crust)

HOT to the touch.

Actually, if you follow the wire emitting thermal energy to it's connection point, and took a picture, I bet somebody could key off that and help.
